I was thinking one of those phonetics along the lines of "Katie Ate Jiff" ... :-)

Do you guys actually use the call signs and the whole HAM etiquette when flying?

How about "Prevail"?

Supposed to be every 10 min but we usually are busy and don't have a clock to go by. Also want to keep chatter to min. Just announce every so often when talking. Saying "mobile" also lets operators know you can't keep track of time or call signs.
